The columellar fold is not so strong as in S. marmoratus ; the spire 

 is shorter than in S. pardalis ; and it differs from both of these, as 

 well as from the other allied species, in the minute sculpture, which 

 is seen only with a strong lens. In the series of 10 specimens before 

 me, the apex is constantly decollated. Been from behind, the lowest 

 suture is noticeably oblique to those above. 



Var. wilsoni Pilsbry. PI. 21, fig. 48. 



Shell with sculpture and general form of moritzianus, but the lip 

 very narrowly expanded, liver-brown ; columella broadly arcuate 

 below, with scarcely perceptible fold above. Yellow, closely zigzag- 

 streaked with brown, spire purple above. 



Alt. 69, diam. 40 mill. ; aperture alt. 39 mill. 



S. GUERINI Pfeiffer. PI. 3, fig. 7. 



Shell imperforate, oblong-ovate, rather thin, irregularly rugose- 

 striate; tawny-brown; spire conic, obtuse, paler, ornamented with 

 streaks and spots of red. Whorls 5, a little convex, the last a little 

 longer than the spire ; columella buff, arcuate, somewhat twisted 

 above. Aperture acute-oval, leaden and very shiny inside ; per- 

 istome narrowly reflexed, buff, the basal lip forming an indistinct 

 angle with the columella. Alt. 41, diam. 18J mill.; aperture, 23 

 mill, long, 13 wide in the middle. (Pfr.').

I am diposed to believe with Reeve, that this is a small form of S. 

 moritzianus. 



S. PARDALIS Ferussac. PI. 19, fig. 36. 



Shell elongated-ovate, rather slender, solid, perforate or rarely 

 closed ; zebra-striped irregularly with purple-brown and white under 

 thin yellow cuticle. Surface with numerous low, inconspicuous 

 rather close spiral cords, malleated between them ; without minute 

 sculpture, or with traces of longitudinal striolation in places. Spire
